An improper authorization vulnerability in PAN-OS that mistakenly uses the permissions of local linux users instead of the intended SAML permissions of the account when the username is shared for the purposes of SSO authentication. This can result in authentication bypass and unintended resource access for the user.
This issue affects:
PAN-OS 7.1 versions earlier than 7.1.26;
PAN-OS 8.1 versions earlier than 8.1.13;
PAN-OS 9.0 versions earlier than 9.0.6;
PAN-OS 9.1 versions earlier than 9.1.1;
All versions of PAN-OS 8.0.
|9.1||< 9.1.1||>= 9.1.1|
|9.0||< 9.0.6||>= 9.0.6|
|8.1||< 8.1.13||>= 8.1.13|
|7.1||< 7.1.26||>= 7.1.26|
CVSSv3.1 Base Score: 5.4 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N)
This issue is fixed in PAN-OS 7.1.26, PAN-OS 8.1.13, PAN-OS 9.0.6, PAN-OS 9.1.1, and all later PAN-OS versions.
PAN-OS 8.0 is now end-of-life as of October 31, 2019, and is no longer covered by our Product Security Assurance policies.
The impact of this vulnerability can be mitigated by removing shared usernames between local linux users and SAML enabled users.
